Reference numeral 1 denotes an agricultural machine body, and an engine 2 is provided at an upper center portion of the aircraft body 1. The transmission is transmitted to the axle 4 in the mission case 3 which is long in the front-rear direction below and the tilling shaft 5 in front of the axle 4 and, as is apparent from the plan view of the main part of FIG. Further, the plurality of tilling claws 7 constituting the rotary K are respectively attached to the both sides of the tilling shaft 5 in the left-right direction so that the tilling work on the field can be performed. ing.

  Further, above the front portion of the transmission case 3, as shown in FIG. 1, a gauge ring 10 is attached to a fan-shaped plate 8 and its mounting posture is adjustable in the vertical direction by a lever 9 so as to face forward. Wearing. The height of the gauge ring 10 is adjusted to move to the vertical and vertical positions of the chain line as necessary, so that the tilling depth can be adjusted.

  Further, in FIG. 1, a handle frame 12 (see FIG. 2) having a width in the lateral direction is firmly attached above the rear portion of the transmission case 3 at a position lower than the vehicle height above the fuselage 1. At the top of the frame 12, there is a steering wheel 13 for driving operation that extends obliquely upward and rearward, and a gear shift that allows the operator O to switch between running speed change and tilling work etc. from the driving operation position along the handle. The lever 14 is extended. The shift lever 14 is configured such that an extension portion thereof can be attached and detached at a midway portion 14a substantially the same height as the top portion of the handle frame 12. As will be described later, an agricultural machine is mounted on an automobile or the like. When the handle 13 is folded, the extension portion is removed so as not to get in the way when the handle 13 is folded.

  In addition, an angle adjusting device 15 is provided at the rotation center C that is the mounting portion of the handle 13 for driving operation, and the operator O arbitrarily adjusts the mounting angle to the height position of the handle 13 according to his / her physique. The handle 13 is folded at an arbitrary position in the chain line state of FIGS. 1 and 2 when the machine 1 is transported or stored, so that the entire machine 1 can be made compact.

  Here, reference numeral 16 denotes a transmission panel for guiding the set position of the transmission lever 14, and the transmission panel 16 is arranged in the middle of the handle frame 12 as shown in FIG. In a state of partially protruding from the bottom portion and substantially orthogonal to the width of the handle frame 12 (see FIG. 1), the shift lever 14 is mounted by bolts 12a and 12a from the outside. The guide 16 is guided in a guide groove 16b drilled in the lateral direction, and is set to a desired speed change / work position.

  Reference numeral 17 denotes a rotary cover that covers the top and both sides of the rotary K, 18 indicates a rotation trajectory of the tilling claw 7 and the tip, and 19 indicates a clutch mounted on the upper side of the handle 13. When the clutch is engaged, a shape is formed along the upper portion of the handle 13 (the solid line state in FIGS. 1 and 2).

  Further, the power from the engine 2 changes the speed change device D accommodated in the transmission case 3 by changing the speed change lever 14 to an appropriate operation position of the guide groove 16b of the speed change panel 16 to change the left and right sides. The details of the transmission device D will be described later.

  Next, the details of the angle adjusting device 15 portion of the handle 13 will be described with reference to FIG. 2. A horizontal support provided with integrated star seats 22a and 22a at the upper and lower ends of the handle frame 12 is provided. A hook 23 is provided, and a loop-shaped handle 13 is integrally provided on the left and right sides of the collars 22a and 22b. The loop-shaped handle 13 is provided integrally with the collars 22a and 22a. By inserting a long bolt 25 penetrating in the left-right direction through each center hole 24... And the inside of the support rod 23, and rotating a knob 26 provided on the opposite side in the left-right direction, The vertical height position of the handle 13 is adjusted by engaging and relaxing the pair of left and right chrysanthemum 22a, 22b.. 1 and 2 By greatly rotating as chain line state, so as it is possible to Hensugata in any position of the transport and storage conditions.

  Further, the rotation center C (the support rod 23 and the long bolt 25 and the like) is disposed above the wheels 6 and 6 constituting the traveling device and at a position lower than the vehicle height. When the handle 13 is folded to the retracted position when it is transported, the operator O can easily hold it because there is no obstacle on the upper part of the support rod 23 serving as the rotation shaft.

  Further, the transmission device D operated by the transmission lever 14 will be described with reference to a sectional view of FIG. Here, FIG. 3A shows the traveling side, and FIG. 3B shows the working side.

  First, the traveling side will be described. The power from the engine 2 enters the input pulley 30 via the belt and is transmitted to the input shaft 31, and the shifter shaft 32 connected to the speed change lever 14 moves when moving forward. As a result, the gear of the input shaft 31 and the gear of the intermediate shaft 33 mesh with each other to transmit power to the intermediate shaft 33, and further to the working machine side intermediate shaft 34 which meshes with the gear of the intermediate shaft 33. Is transmitted to the output shaft 35 through the gears, and is transmitted to the axle 4 through the operating gear device 36 here.

  On the other hand, when the shifter shaft 32 moves backward, the shift shaft 32 moves, and the gear of the input shaft 31 different from that when the input shaft 31 moves forward meshes with the gear of the reverse shaft 37. Since power is transmitted to the gear and reverse power is transmitted to the intermediate shaft 33, the gear of the intermediate shaft 33 rotates in the reverse direction and transmits power in the same way as in the forward movement. 4 reversely rotates and the airframe 1 moves backward.

  Also, the working side will be described. When the vehicle body 1 is moving forward and working, the shift lever 14 moves the shifter shaft 32 so that the vehicle body 1 moves forward and the input shaft 31 travels. Further, another gear meshes with a gear other than the traveling loosely fitted to the intermediate shaft 33 to transmit power, and the work implement is connected via the gear of the work implement-side intermediate shaft 34 meshed with the gear. Power is transmitted to the side intermediate shaft 34, and is transmitted from the sprocket 38 at the center of the work machine side intermediate shaft 34 to the sprocket 40 on the tilling shaft 5 side via the chain 39, and a pair of left and right differential gear devices 41, 41 are transmitted. Are transmitted to the left and right tillage shafts 5 respectively.

  The thing of this invention consists of the above structures, and when performing a normal farming work etc., what is necessary is just to carry out in the work position (solid line position of a figure) where the handle | steering-wheel 13 was stood up. Is different. In such a case, the knob 26 of the angle adjusting device 15 in front of the operator O is loosened to temporarily unlock the pair of seats 22a, 22b,... Provided on the rotation shaft (support shaft 23) of the handle 13. After the angle of the handle 13 is adjusted to a height that matches the physique of the operator O, the handle 13 is fixed to an appropriate height by locking the pair of chrysanthemum seats 22a, 22b,. Is done.

  Further, when the airframe 1 is carried in an automobile, the knob 26 of the angle adjusting device 15 is loosened to unlock the pair of star seats 22a, 22b, and the handle 13 is moved forward. The knob 26 may be tightened after being largely folded and rotated to the folding position (dotted line position in the figure). At this time, the rotation center C of the handle 13 relative to the handle frame 12 is located above the travel device and lower than the vehicle height.

  Further, the power of the engine 2 is transmitted in an appropriate movement / working state by moving the transmission lever 14 along the guide groove 16b of the transmission panel 16 to move the gear inside the transmission D. The transmission panel 16 is not attached to the width of the handle frame 12 and protrudes to the outside, and the rotation center C of the handle 13 at this time is higher than the transmission panel 16.

  Therefore, according to the present invention, when the handle 13 is rotated with respect to the handle frame 12 and the walking-type agricultural machine H is transported, for example, for mounting in an automobile, the operator O can rotate the rotation axis of the handle 13. It is possible to carry the walking type agricultural working machine H with an easy posture.

  Further, when the handle 13 is rotated to carry the walking type agricultural machine H, the shift panel 16 is not obstructed, and the handle can be easily rotated with the shift panel 16 attached to the handle frame 12. The effect which can be done is produced.
